Abstract: A layered stripline filter has input and output electrodes formed on a dielectric layer, two resonant elements disposed on the dielectric layer and having ends connected to a ground electrode, providing a quarter-wave stripline resonator, an inductive coupling adjustment electrode disposed on the dielectric layer intermediate between the two resonant elements and having opposite ends connected to the ground electrode, and a coupling electrode disposed on the dielectric layer in overlapping relationship to portions of the two resonant elements. The layered stripline filter is small in size and has a desired bandwidth achieved by adjusting the inductive coupling between the two resonant elements. The layered stripline filter has an attenuation peak spaced from the passband thereof, resulting improved attenuation and spurious characteristics.
